Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a solid mold casting coating with strong wear resistance and a preparation method thereof. Background technique [0002] The solid casting coating is a dispersion system composed of a variety of materials with different properties. Its composition mainly includes refractory materials, binders, carriers, suspending agents and special additives. It is required that the coating has good process performance, work performance and quality. Stability and application reproducibility. The solid casting paint is coated on the outer surface of the foam plastic model, and the molding can only be poured after the paint is dry. Foamed plastics are airtight, have a low heat distortion temperature (about 70°C), and have poor affinity for water; foamed plastics are heated and melted, and after gasification, there are many liquid residues and a large amount of gas generation. If these gases and...
